This pendant has touched the edge of space. On Aug. 29, 2023, the students of Earth to Sky Calculus launched it to the stratosphere onboard a cosmic ray research balloon, more than 119,010 feet above California's Sierra Nevada mountains.
Engraved with the words "I love you always and forever", this 18K gold-plated sterling silver pendant has a heart-shaped ruby crystal in the middle surrounded by a heart-shaped ring of glittering 5A cubic zirconia nuggets. It is a visually striking premium pendant that makes a once-in-a-lifetime anniversary or birthday gift.
During the 2.3 hour flight, the pendant experienced temperatures as low as -58 C and air pressures less than 0.09% of sea level. According to onboard radiation sensors, cosmic ray levels were 100 times Earth-normal as the pendant reached the top of our planet’s atmosphere and touched the edge of space. After the balloon exploded (as planned), the payload parachuted back to Earth, landing in the White Mountains overlooking Bishop, CA.
The students are selling space pendants to pay the helium bill for their cosmic ray ballooning program. Each one comes with a greeting card showing the jewelry in flight and telling the story of its trip to the stratosphere and back again.
